To aZZ whom, it may concern.:

.lle it known that I, GEORGE lV. VHI'TE, a citizen of the United. Sta-tes, residing at ivaco,

partly round or iu anyv other desired shape. This cylinder or tube is ina-de, preferably, with one closed solid end, d, and with a. removable in Idie county of McLennan and State of Texas, plu glii e cap, d', at the other end, so 'that access 5 5 have invented a Fire-Clay Heater, being a 1 may be had to its interior. The cap d is procertain new and useful invention for the purl vided with ay fastening-recess, at its edge, pose of burning brick` in kilns for heating l and the cylinder is formed with a correspondsteanrboilers, stoves, grates, and lire-places; i ing lug, @which t-s into said recess, as shown, and I do hereby declare that the following is a i and holds the cap in place. Instead of the 6o 10 full, clear, and exact description of the invencap d', with its recess f, and the lug e on the tion, which "will enable others skilled in the l cylinder, a cap with a screw-thread, d2, Figs. art to which it appertains to make and use 5 and 7, maybe adopted. 'lhe jet passages the same, reference being had to the accom* or perfora-tions l1 in the cylinder extend rapanying drawings, and to the letters of referdially from the interior to the periphery of' 65 ence marked thereon, which form a part ot" the cylinder and maybe placed all around, this specification. as in Figs. T and S, or partly around, as in My invention consists in an improved lirc- Figs. 5 and 6, or all around, except at the log burner for oil or other fluid or gaseous bottoni 7i, Where the cylinder is flattened, so inflammable substances, said burner being in as to rest iirlnly upon the'strueture which 7o zo forni of a tube or hollow cylinder, and made supports it, as shown in Figs. and The of iire-clay, and provided with numerous size and number of the passages will be in jet or burner passages in its periphery, and proportion to the length and diameter of the `filled with connninuted asbestus or other cylinder and the purpose for which it is used.

Through the plug-closed'end of So 3o places, and for other analogous uses. the cylinder asbeslus or other fluid-absorbent ln the drawings, Figurel represents my inlire-proof material in a eomininuted form, as Vvcntion in elevation. Fig. 2 is avcrtical sccl small fibrous pieces, is placed in the chamber tion in thcline l'jof lfig. l, the log being shown i of; the cylinder, so as to fill the same, as indiresting on andirons. Fig. 3 is a crosssection l cated at-g. The asbestos will not be so tightly 85 in the line 7; Z of Fig. l, the log being shown l packed as to prevent the flouv ol the fluid by resting on andirons; and Fig. l, a detail plan capillary attraction through and between the vieuot' the removable cap or plug of the firei particles from the supply-passage to the jet log burner. Fig. is a longitudinal section of passages or perforations; but its particles a modilication of the invention, showing a i should be close enough together to prevent a 9o 4o round fire-log burner with screw-plug cap and too rapid floiv of the llnid and effect its disperforatcd partlyVY around; and Fig. (Sis a crosstribution in very minute streams at the jetsectional view of the log.

The Within-described cylindrical or tubular fluid-burner log` may be used singly or in any number desired. For burningl brick or heatingboilers they ean he placed in The combustion ella-inheror chambers olf any eonnnon kiln, Il, as illuslral'ed in Fig. il, or any furnace, they extending' nearly or qu ite the entire length el The chamber, and projecting,` at one end, A', four or six inches outside the wall or casing', so as to be kept cool aty the point where l the supply-tul e c is introduced. The easing or Wall around the log' should of Course be air-tight.

These logs can be used in the saine Way for steam-boilers or heating-dues, and when made smaller can be used in the saine Way described.
